<div style="direction: ltr;font-family: Arial;color: #000000;font-size: 10pt;">Hi all<br>
<br>
I ran into some problems while implementing an asynchronous interface towards the ds485 stack.<br>
First I register some callbacks.<br>
When they all return OK, I start scanning the bus for available devices.<br>
<br>
Some problems using the following example code:<br>
- the localBusStateCallback is used.<br>
- the localZoneDeviceCountAll is not used, yet I always receive synchronous answers (log sattements)<br>
- localDeviceInfoByIndex is not used, yet I always receive synchronous answers (log statements)<br>
<br>
Does anybody have some more experience with the asynchronous calls?<br>
<br>
EXAMPLE CODE:<br>
OneStatus_t localRegisterCallbacks(void)<br>
{<br>
DsmApiCallback_t cbStruct;<br>
cbStruct.arg = NULL;<br>
cbStruct.function = (void*)&localBusStateCallback;<br>
if(DsmApiSetBusStateCallback(apiHandle, &cbStruct) != ERROR_OK)<br>
{<br>
TRACE;<br>
return One_Failure;<br>
}<br>
<br>
cbStruct.arg = NULL;<br>
cbStruct.function = (void*)&localZoneDeviceCountAll;<br>
if(DsmApiSetCallback(apiHandle, DS485_CONTAINER_RESPONSE, ZONE_DEVICE_COUNT, ZONE_DEVICE_COUNT_ALL, &cbStruct) != ERROR_OK)<br>
{<br>
TRACE;<br>
return One_Failure;<br>
}<br>
<br>
cbStruct.arg = NULL;<br>
cbStruct.function = (void*)&localDeviceInfoByIndex;<br>
if(DsmApiSetCallback(apiHandle, DS485_CONTAINER_RESPONSE, DEVICE_INFO, DEVICE_INFO_BY_INDEX, &cbStruct) != ERROR_OK)<br>
{<br>
TRACE;<br>
return One_Failure;<br>
}<br>
<br>
LOG("ds485 callbacks are registered.\n");<br>
return One_Success;<br>
}<br>
<br>
OneStatus_t localScanBus(void)<br>
{<br>
OneStatus_t status = One_Failure;<br>
<br>
uint8_t result;<br>
dsid_t members[DS_MAX_CIRCUITS];<br>
<br>
if((result = DsmApiGetBusMembers(apiHandle, members, DS_MAX_CIRCUITS)) > 0)<br>
{<br>
// filter out the meters<br>
for(uint8_t i = 0; i < result; ++i)<br>
{<br>
if(DsmApiIsdSM(members[i]))<br>
{<br>
uint16_t numberOfDevices;<br>
// USE ZONEID 0 = BROADCAST TO ALL ZONES<br>
if(ZoneDeviceCount_all(apiHandle, members[i], 0, &numberOfDevices) == ERROR_OK)<br>
{<br>
LOG("Requesting ZoneDeviceCount_all\n");<br>
LOG("Devices found: %d\n", numberOfDevices);<br>
for(uint16_t index = 0; index < numberOfDevices; ++index)<br>
{<br>
uint16_t deviceId;<br>
if(DeviceInfo_by_index(apiHandle, members[i], 0, index, &deviceId, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL, NULL) == ERROR_OK)<br>
{<br>
LOG("DevicesInfo for device: %d\n", deviceId);<br>
status = One_Success;<br>
}<br>
}<br>
}<br>
}<br>
}<br>
}<br>
<br>
return status;<br>
}<br>
